I am a postdoctoral researcher at National Taiwan University. I received my doctorate in 2013 from National Taiwan University. During my Ph.D. study, I worked closely with my advisor Jieh Hsiang at the Department of Computer Science and Information Engineering on natural language processing and information retrieval. I have also spent an year visiting University of Southern California, working with Andrew Gordon at the Institute for Creative Technologies on topic modeling and cluster analysis. Prior to that, I worked full-time as a research assistant at Academia Sinica, in Lee-Feng Chien's group at the Institute of Information Science. Our research work focused more on information retrieval and web mining.
I received my B.S. and M.S. from National Taiwan University in 2001 and 2003, respectively.

I am actively developing and maintaining the following software packages:
This is my curriculum vitae.
I am a classic rock fan, a bassist, and a Linux user.
Like beers and math. (Who wouldn't?)
Since late 2011, I have officially become the in-house babysitter for my little boy.
